The box body plastic sheet and handle plastic sheet respectively form the box body and handle. The box body can be made up of one to three plastic sheets with cut grooves, cut lines, insertion and protruding ears, foldable trace and position-fixed trace, handle hole, which can be folded or squeezed into a square body or cylindrical box. The handle plastic sheet has the foldable trace or cut lines, and insertion and protruding ears that can be squeezed mutually to link together.

Claims

1. A package box capable of being folded for use and unfolded for storage, and formed of moisture proof and printable material, which box comprises:

(a) a first sheet formed of plastic material and provided with a plurality of first traces defining lines along which the first sheet may be folded to form a rectangular-shaped box;

(b) the first sheet including;

(i) a plurality of corresponding ear and slit assemblies which may be detachably engaged for securing the first sheet in its folded position,

(ii) a pair of opposed side walls, each side wall including a circular shaped aperture;

(c) a second sheet formed of plastic material and in the configuration of an elongate strap for defining a handle, each end of the strap including a pair of oppositely directed semicircular slits defining a pair of inwardly foldable semicircular-shaped locking ears; and

(d) each end of the handle being securable to the box by inserting each pair of semicircular-shaped locking ears through a corresponding circular aperture, thereby permitting the handle to pivot about the circular apertures.

2. A package box capable of being folded for use and unfolded for storage, and formed of moisture proof and printable material, which box comprises:

(a) a first sheet formed of plastic material and provided with a plurality of engagable ear and slit assemblies which may be detachably engaged for securing the first sheet in a folded position to form a cylindrical-shaped box, the upper and lower ends of the box being provided with a plurality of circumferentially spaced slits and a pair of circular apertures in opposed wall portions of the box;

(b) second and third sheets formed of plastic material for defining the top and bottom of the box, each of the second and third sheets being provided with a plurality of outwardly extending tabs engageable within the circumferentially spaced slits of the first sheet;

(c) a fourth sheet formed of plastic material and in the configuration of an elongate strap for defining a handle, each end of the strap including a pair of oppositely directed semicircular slits defining a pair of inwardly foldable semicircular-shaped locking ears; and

(d) each end of the handle being securable to the box by inserting each pair of semicircular locking ears through a corresponding circular aperture, thereby permitting the handle to pivot about the circular apertures.
